False Swipe > Leech Seed.

False Swipe allows you to knock them down to 1 HP without a KO, guarenteed.

Since most roamings don't have recoil moves, use that.

Another factor is that you may want to keep the mon asleep.

Those will maximize your chances, but a legend has an intentionally low catch rate.
